DEVICE FOR MAKING TAP connncrions To wA'rnaMAms.

Application filed July 2,81,

The invention relates to devices for drilling and tapping water mains and the like and for securing bolts in the holes made therein so that tap` connections may be secured to the main.

In practice, it is necessary in many ini stances to make tap connections to water mains while the mainis in use or filled with water. In installing these connections, it is necessary to form Vtapped holesfin the water main for the boltsbywhich the tap fitting will be secured thereto.

Gneobject of the present inventionv is to provide a device for drilling andtapping holes andrwhich is adapted for connection to awater main or the like and operative thereon without turning off the water sup-V ply therein or permitting' the water to escape. Another object of the invention is to provide a device which can be easily manipulated and is adapted tol expedite the labor required ,in making tap connections. Other objects will appear from Vthe specification.

The invention consists in the several novel features hereinafter setA forth andk more particularly `defined 4by claims at the conclusion hereof.

In the drawings: Fig. 1 is a vertical section of the invention applied to a waterV main. Fig. 2 is a front' elevation of the invention. Fig. 3 is a plan view. 4 is a detail section of the cam which holds the cap vand casing in fluid-tight connection.

In applying tap connections, in accordance with Letters Patent No. 1,317 ,87 O, granted to me, October 7, 1919 and `nsing the attaching bolts as set forth in application No. 530,628, filed by me, January 19, 1922, it is necessary to drill and tap holes in the waterinain for the attaching bolts or `devices whi kh Vsecure the fitting of the tap connection to vthe main. The present invention is illustrated in connection with a `device 4for drilling and tapping the holes in the main and securing the threaded attaching bolts or sleeves therein preparatory to pair of elongated bosses and 3-1 id issecuring the tting thereon, y The .invention is!

tight connection between the-.end of casing 9 rand main 11. A pair of lugs 14: are lintegrally -formedwith casing 9 and are disposed diametrically opposite each other in the axial planeJ of main 11, and each is provided with an opening 15 through which the shank of a bolt 16 is adapted to pass. The lower end of' each bolt 16 is `provided with a hook portion 17 on which the ends of iiexible chains 18 arevsecure'd respectively. These chains are adapted to extend circumferentially around ina-in 11 `so as toposition and hold the casing securely against the main 'when the device is in use.` rlihe shank of each b olt is provided with a screwthreaded portion 20 adapted to be engaged o n the end projecting through the lugs by a nut 2 1. By rotating nuts '2,1 with ,a snit-a'- ble tool, the tension on ,chains'18 he regulated so as toposition and hold the end of casing 9 in `huid-tight connection with the main and to ixedly secure it thereon. The outer vend of casing` 9 is open and is adapted to he closed by ar rotatable ca pl which is providedwith an inwardly extending yannular iiange 24 adapted to ysnugly engage thefout-er periphery of'casing 9. Then is use, al Huid-tight connection is inaintainedby the inner face,` of cap 23 and the outer yend of casing 9 by means of devices 26. Each of said devices (as shown in Fig. Ll) comprises a stnd27 with a cylindrical portion`27a adaptedV to rotate in a bearing 281in flange 24. 'The Vouter end of each studextends through the flange and is provided with a handle 29 by which the stud 27 may be manually rotated.` 'Ilhe inner end of stud 27 is provided with a pin 3 0 eccentrically mounted on portion 27@ and which extends into annnlar groovev31 on-the outside of casing 19. vBy rotating the handle 29, the cap 23 may be forced 'into and held in fluid-tight connection with kthe end ofcasing 49 or'l it-Vinay lbereleased sufficiently Vto permitthe can to bek rotated.

'The'ou-terendfof cap 23 is provided with h is hel scretv 39 secures the drill in the socket.. The outer end of shaft 36 is formed l-With a shoulder L.l1 which is adapted to engage a coacting shoulder or constricted portion 42 to prevent theshaft frombeing pulled out Wrench or. any other suitable tool for rotatcap 23 andboss 34.

ingthe shaft end Boss 33 is provided on its outer periphery With'an external screw-thread 60 on which isdispos-ed a device for feeding thev shaft 36 with the combined drill and Vtap downwardly.kv This device comprises a ring 61 provided With an internal.screw-thread Which is adaptedto engage thread 60.v A kbail 6e is pivotally mounted at one end to rings 61 by means'of pins 65 and at the other end is provided with a yoke adapted to engage acollar or shoulder on shaft-36 Handles 63 Vare rigidlysecured to ring` 61 for manually rotating the ring so that when the shaft 36 y.is turned by means of a Wrench, downward vpressure may Vbe applied to the shaft.` Y A shaft V51 extends through a hole 5t)V in This shaft extends Withinthecasing and is providedat its inner end with an internally threaded socket An attaching bolt or sleeve, such as shown in the aforementioned application No. 530,628, filed byme, January 19, 1922, is loosely held in said socket.v The outer end of shaft 51 is provided with a shoulder 54 which is; adapted to engagea shoulder 55 on boss V3ft tolimit the outward movement of the shaft. A packing-box around shaft 51 preventsleakage of Water from the casing 9.y The outer end of shaft 51 is suitably 'formed for connection to a Wrench or `other rotating tool, so'that the shaft 51 with the attaching .bolttherein may be rotated. A collar 58 may-.be secured on each ofthe shafts 51 and 36 toflimit theinward movement thereof.' Y,

In use, when it is ldesired. to secure a tap connection to a Water main, an attaching bolt or sleeve is loosely'secured in socket 52 of shaft 51 and a combined drill and tap inserted' inthe chuck on the endof shaft '36.l Capf23is then brought intoposition to bring-thecombined drill and tap onthe end of shaft 36 in line with the place to be drilled and then by manipulation and operation vof the-devices 26, the` cap is rigidly secured "to the' top of the casing in fluid-tight connection. The 'casing9 is then secured on the main'by 'means of the' chains 418and `fixed thereto; byV means 'of tightening nuts 2l. The bail 64 may then be 'raised so that 36 with the tool on its inner nection the yoke engages collar 65.'. Shaft 36 is then turned and by rotationof ring 61 sutHc-ient pressure is exerted upon to drill and tap the main.. After this, the devices 26 may be loosened suflicientlytopermit cap 23 to be rotated 180o until the shaft 51 with the attaching bolt is in line with the drilled and tapped hole.v The shaft 51 is then turned and the bolt inserted in the hole. By reversing the rotationy of the shaft, the socket 52 may be Withdrawn from the bolt. This operation maybe performed until the desired number of attaching lugs have been secured in the main, andthe tapconnection Secured thereto.

'f a tap connection such as exemplified inthe aforementioned Letters Patent- No. 1,317,870, granted to me, October?, 1919, is desiredto be connectedto amain, two attach'- ing lugs' may be secured' inthe main'and the iitting bolted thereto. ff' The valve in the fitting may then be openandthe main drilled through the valve openingL As soon as a hole has been completely drilled therethrough, the ldrill may be removed through the littingand the valve closed/so that the Water will notescape from* the main.The necessary connections to the tap fitting may then be secured so *asto complete the vcon- 9! The. invention exemplifies a -device vfor drilling-andl'tapping holes in Water mains andv securing attaching lugsrtherein so that tap connections may *bei secured to the main Without permitting the escape of Water 100 or turning olf thesupply in the main; The invention is not to be understood as restricted to the detailsset forth, sincethese maybe mo'diiied Wit-hin the scope of the appended claims, Without,l departing from the siiiirit and scopeyof the invention.

Having thus described the invention, what .l claim as new'. and desire to secure by i Letters Patent, is: l i 1. ln a device of the character described., the combination of a casing consisting of ya substantiallycylindrical Wall having open ends, means for` rsecuring oneend of the casing against a Water vmain, a' head rotatably yn'iounted on the other yend of said 115 casing and having anV annular Wall extendtowards the main and disposed adjacent the casing Wall, means mounted in the head1 and* extending throughthe casing for drilling a hole in mounted inthe head for inserting abolt in the hole, one ofusaid Walls being provided'with an annular groove, and means mounted in the other Wall and extending into said groove for lshifting the head axially intofluid-tight engagement with the said other end ofthe casing.
